Bi-truncation for simplified MIMO signal detection
The joint maximum-likelihood (JML) detector may be used in memoryless multiple input multiple output (MIMO) systems to obtain optimal detection performance. However the JML detector needs an exhaustive search and causes prohibitively large decoding complexity. To reduce the complexity of MIMO signal detection, the minimum mean-square-error (MMSE) linear detector (LD), decision-feedback detector (DFD) and sphere detector (SD) may be used. In this paper we develop bi-truncation based approaches for MIMO signal detection. The new approaches have low-complexity, and computer simulation results show that they outperform MMSE-LD and MMSE-DFD.
